The Team Alba Pipe is a the Best pipe out.
I did a Pipe Test with all of the 4 Stroke Pipes befor I bought one and I liked the Alba pipe Better.

 

It does need to be rejetted if you plan on K&N filter on it, i'll laugh if you are on here because you were running lean and screwed something up in your quad, the more airflow you have the more fuel flow you will need.

 

Do you like the looks of the Alba pipe. And does it come as a full system for $259.99 or is that just a slip-on.

 

what all could happen if you didnt rejet it?

 

Yes I like the Looks of the Team Alba Pipe. And with the Kit you get the Pipe, Torque Stuffer, K&N Air Filter, Outerwear, and Jetting for $269.99. And it is a slip on pipe.
And about not rejetting you could seize up you Motor.
